摘要： An Organic Light Emitting Display (OLED) and its fabrication method has a pixel defining layer provided on a first electrode which is formed with a gas vent groove to allow gas to vent when the pixel defining layer is being formed, so that gas is not left in a pixel but vented when a donor film is laminated by a Laser-Induced Thermal Imaging (LITI) method, thereby decreasing edge open failures.

摘要： A laser irradiation device and a method of fabricating an organic light emitting display device (OLED) using the same are disclosed. The laser irradiation device includes: a laser source generating a laser beam; a mask disposed below the laser source and patterning the beam and a projection lens disposed below the mask and determining magnification of the laser beam through the mask, wherein the laser beam penetrating the mask has different doses in at least two regions. Thus, the laser irradiation device can maximize emission efficiency and enhance the quality of a transfer layer pattern when an organic layer of the OLED is formed using the laser irradiation device.

摘要： A laser irradiation device includes a laser generator for patterning and a laser generator for preheating. A laser induced thermal imaging (LITI) method, includes preparing an acceptor substrate, laminating a donor substrate on the acceptor substrate, and irradiating a laser beam onto a predetermined region of the donor substrate and carrying out transfer using a laser irradiation device having a laser generator for patterning and a laser generator for preheating. Advantageously, a laser beam having high intensity generated by the laser generator for patterning is used to prevent the transfer layer from being degraded, and a laser beam generated by the laser generator for preheating is simultaneously used for preheating so that an edge open failure does not occur and the transfer can be readily carried out even in a portion having a step of the acceptor substrate.

摘要： A method of fabricating a donor substrate for a laser induced thermal imaging (LITI) process. A base substrate is prepared. A light-to-heat conversion layer is formed on the base substrate. A buffer layer is formed on the light-to-heat conversion layer. The surface roughness of the buffer layer is increased by treating the surface of the buffer layer. A transfer layer is formed on the surface-treated buffer layer. By using the donor substrate, a patterning process can be performed better during the fabrication of the OLED.
